A:Answer The LG - 55" Class (54.6" Diag.) - LED - 1080p - Smart - HDTV - Black, Model # 55LH575A has an HDMI IN and HDMI IN/ARC port that can be used to connect to external devices that have those ports as outputs. It also has a port labeled the 'Shared Composite/Component Video Input.The number of Component and the decades-long standard bearer, Composite, video connections are now few in number and have been consolidated into a single video input option referred to as a "Shared Composite/Component Video Input". The TV's video input circuitry has been modified so that both a composite (also referred to as RCA ports) and a component video source can be accommodated. You just can't plug both a composite video and component video signal source to the TV at the same time. You can still plug your VCR or older DVD player to the TV using this port, but not both at the same time. You can check to see what output you have on your DVD Player to determine if you can connect it to the available inputs described above that are on the TV or refer to the owner's manual for the DVD player which will instruct you on how to connect it to a TV...^IFV
